1 Claim.

This invention relates to a lifting apparatus especially adaptable foruse as a fishing pole in connection with commercial iishing for largegame fish such as tuna, sea bass and albacore and is particularlyadaptable for use with such nsh which weigh in excess of one hundred andnity pounds and which can not be landed or brought to gaff by shermenwith rod and reel, without danger of injury to the fishermen and which,in the past, has frequently required as many as four men to boat such afish.

More particularly, it is an aim of the present invention to provide afishing pole formed of telescoping sections which are adapted to beextended by a pressure medium and which is provided with means causingthe pole to be swung upwardly and inwardly over the boat, to which it isconnected, when pressure is applied to the pole, so that a sh, hooked toa line connected to the pole will be raised out of the water thereby andswung into the boat without the necessity of gaffng and in such a manneras to substantially eliminate the danger of the sh striking the boat andbecoming unhooked.

More particularly, it is an object of the presu ent invention to providea pressure actuated apparatus for hoisting and swinging a load and whichis readily adaptable for use as a derrick or boom and which is capableof being made in various sizes for accommodating various loads.

Various other objects and advantages oi the invention will hereinafterbecome more fully ap parent from the following description of thedrawings, illustrating a presently preferred embodiment thereof, andwherein:

Figure 1 shows the invention in side elevation in a preferredapplication and use thereof as a iishing pole;

Figure 2 is an enlarged top plan view thereof;

Figure 3 is a vertical sectional view taken substantially along a planeas indicated by the line 3-3 of Figure 2;

Figure 4 is a sectional view taken substantially along a plane asindicated by the line *4 of Figure 3 and showing the apparatus in,endelevation and looking toward the inner end thereof;

Figure 5 is a longitudinal sectional View, partly in side elevation andshowing the pole in a retracted position;

Figure 6 is a view similar to Figure 5 and show@ ing the pole in anextended position;

Figure 7 is a fragmentary longitudinal, central sectional View of theintermediate portion of the pole;

Figure 8 is a cross sectional view of the pole f' a novel shing pole orlifting apparatus, designated generally I Il and comprising theinvention, includes an elongated pole preferably formed of tubulartelescoping'sections II and I2, as best seen in Figures 5, 6 and 7.

The inner pole section II is closed at its inner end and is providedwith an open, externally threaded outer end I3. The outer pole section I2 preferably includes an inner tubular portion I l of substantiallyuniform diameter throughout its length andof a small external diameterthan the internal diameter of the pole section I I, and an elongated,tapered tip I5 which is likewise preferably hollow and closed at itsouter end and which preferably has a restricted nipple I6 at its innerend which extends into the outer end of the tubular portion I4 and issecured thereto by suitable fastenings I7. The inner end of the tubularportion IQ has a disc I8 secured thereto in any suitable manner as bywelding at I9 and which forms the headed inner end of the outer polesection I2 and is sized to reciprocally engage in the inner section Il.A bolt 20 extends through the central portion of the head It and througha central bore of a relatively thick disc of rubber or other suitablematerial 2| which is clamped against the exposed side of the head I8 bya nut 22 which engages a threaded shank end of the bolt 2t. The rubberdisc 2| islikewise adapted to slideably engage closely Within the boreof the inner pole section II and forms a sealing member, for a purpsewhich will hereinafter become apparent. A retaining collar 23 isrotatably disposed on the tubular element I4 and is provided with anenlarged internally threaded end which threadedly engages the threadedend I3 of the pole section I I and is retained thereon by a setscrew 24which extends radially through the threaded portion of the collar 23 andinto engagement with the threaded end I3. The head I8 is larger indiameter than'the bore portion of the collar 23 which slideably engagesthe tubular element I4 so that collar functions as a stop to limit theoutward telescoping movement of the pole section I2 relatively to thepole section II, as indicated inFigures 6 and '7.

As best seen in Figures 2, 3 and 4, a mounting bracket 25 is adapted tobe fastened to the gunf wale 26 of a boat 2l, which is partiallyillustrated, and said bracket 25 is provided with spaced upstandingapertured ears for receiving therebetween an apertured extension 28which is formed integral with or suitably secured to the inner closedend of the pole section II and which is connected to the bracket 25 bypivot pin 29 which extends through the aperture of said extension or arm28 and through the apertured ears 30 for pivotally or swingably mountingthe fishing pole I l) on the gunwale 26.

The fastening fil projects at both ends from the pole section I2 forpivotally mounting the ends of a U-shaped yoke 3| which is provided withan outwardly projecting eye 32, intermediate of its ends, to which isanchored one end of a iiexible hoisting element 33 which extendsinwardly therefrom through an eye 34 of an arm 35 which extends inwardlyand upwardly from the mounting 25 as best illustrated in Figures 3- and4 and which is preferably formed integral with the mounting 2E butwhich, could form an extension of the rod arm 28 and in which case itwould swing therewith rather than being iixedly supported relatively tothe gunwale 26 with the mounting 25. The iiexible member 33 afterpassing through the eye 34 extends downwardly and has its opposite endanchored to any suitable part of the boat 2, as by means oi; the eyebolt 3S but preferably beneath and adjacent the mounting 25.

The pole section i I adjacent its inner or closed end is provided with anipple 3l to which a hose or flexible conduit 38 is connected. The hose3S extends therefrom and is connected at its opposite end, not shown, toa suitable source of a compressed pneumatic or hydraulic medium, notshown. The outer end of the tip portion l5 of the pole is preferablyprovided with an outwardly projecting eye 39 to which a fishing line 40is adapted to be attached, as by means of a snap fastening, or by beingtied directly thereto, and the opposite free end of the line G isattached to a sh hook FII. If desired, and as illustrated in Figure 9,the tip I can be provided with an eye 112 located on its under side andadjacent its outer end in lieu of and for the same purpose as the eye 39or it will be readily apparent that the fishing line d@ could be passedthrough guides along the upper side of the rod I0 and attached to a reelor winch by means of which the line could b-e payed out or wound inrelatively to the iishing rod, if desired.

From the foregoing it will be readily apparent that the fishing rod Iwill normally be supported in its full line position of Figure 1 by theexible member 33 and with the pole section I2 fully retracted. Thusdisposed, the line lil is adapted to be of suicient length so that thehook 6I and bait, not shown, which it may carry will be trailing in thewater. When a iish is caught on the hook di the operator of the rod I@.by admitting the compressed medium, such as compressed air from astorage tank within the boat to the hose 38 will cause the rod sectionII to be lled with the compressed air behind the piston or seal 2l andthe pressure of this air or other compressed medium, which can equallywell be an hydraulic fluid, will cause the rod section I2 to beprojected outwardly of the section II for extending the rod. Thisextension of the rod IQ, which will be gradual, will also cause the rodto swing upwardly in order to take care of the fact that the cable orflexible member 33 is not extensible so. that in order to permitextension of the rod said rod must swing on its pivot 29 to enable theeye 32 of the yoke 3l to remain at the same distance with respect to theaperture Sli of the arm 35 so that by the time the rod IS has reached afully extended position it out of the Water and swung over the gunwale26 to a position over the boat 21 so that when the compressed medium isreleased from, the pole section II, which can be accomplished by asuitable bleeder valve, not shown, adjacent the source of said medium,the rod I0 will be returned to a retracted, telescoped position by theweight of the sh and which will thus cause the iish to be lowered intothe boat. It will thus be readily apparent that the rod Ill eliminatesthe necessity of using a gail in boating a large fish and likewiseeliminates the need of manually landing the sh which, frequentlyrequires three or four men whereas the shing rod IIJ can be operated bya single man.

It will also be readily apparent that the rod I0 can be used with a linewhich i5 slidcably connected thereto and attached to a power driven reelor winch within the boat 2,1 so that a sh could be drawn in close to theboat and therea ter swung aboard by the rod IQ., The rod IU could alsobe utilized in connection wih sport fishing by attaching a gai to theline 4 0 and after a fish had been brought. to a position to be gailed,the rod I0 could be utllizzd as previously described for swinging thegafed fish intov the boat.

It will likewise be readily apparent that theapparatus I0 is equallywell adapted to be used as a derrick or boom for lifting and swingablyconveying various loads as its use as a fishing rod merely illustratesone class of load adapted to be lifted and conveyed thereby.

Various other modications and changes are likewise contemplated and maybe restorted to, without departing from the spirit or scope, of theinvention as hereinafter dei-ined by the appended claim.

I claim as my invention:

A hoisting and conveying apparatus comprising an elongated hollow memberformed of telescoping tubular sections deiining a closed cham-y ber andincluding an inner section and an outer extensible section, means forpivotally mounting said member adjacent an end of said inner section ona supporting structure, an arm fixed to and projecting from the pivotedend of the member and disposed at an angle thereto and extending in anupward direction when said member is disposed in substantially ahorizontal plane, a
